Free serial ws v2.0 software for linux

Serial Over IP is a tool for the transport of serial interfaces over UDP/IP. It is very usefull for connecting distant equipment that run via a serial interfaces to a local computer.


One linux will be server and one will be client. On the server you can start the program typing the following command:

bash# serialoverip -d /dev/ttyS0 9600-8n1 -s 127.0.0.1 3000

... and on the client:

bash# serialoverip -c 127.0.0.1 3000 -d /dev/ttyS1 9600-8n1

In both commands the IP address is the server IP. Note that you have to start the server first, and it will be efectively be running only after the first packet received from the client.

WIGS is both an API to talk to a GPS receiver over the serial port via the NMEA protocol supported by most GPS receivers, as well as an application that use this API.
The first phase of the WIGS project is now completed as weve published the API.
The second phase is to make an application to present the data received from the GPS in a simple and intuitive way.
The third phase, and also the most important phase, is to add a special mapping feature which allows the user to load any scanned map and, as long as that map is calibrated by providing a set of known coordinates on that map (usually the corners of the map), present the users current position on that map.
Enhancements:
- The API was completely rewritten for better integration into the GUI.
- Third party communications drivers written by developers other than the development team are supported.
- Some minor bugs were fixed.

PoTerm is serial terminal shell talks to serial ports and it is capable of sending AT commands to modems. A serial communication library is also available. Works on Windows and Linux also.
Enhancements:
- An enhanced cmd shell provided to intaract with serial port
- A serial communication library
- connection profile saving, log support (loglevels also) available
- serial sessions can be established using single commands (useful when sending "at" commands using perl, tcl, etc scripts)
- not tested on linux

The ser2net daemon allows telnet and TCP sessions to be established with a units serial ports. Note that ser2net supports RFC 2217 (remote control of serial port parameters), but you must have a complient client. The only one I know it is kermit application (http://www.columbia.edu/kermit).
Enhancements:
- dataxfer.c, devcfg.c, devcfg.h, ser2net.conf, ser2net.8: Added a s banner token for printing out the serial parameters.
- ser2net.conf: Cleaned up the ugly banner3.
- Makefile.am: Add ser2net.init to EXTRA_DIST.
- configure.in: Move to version 2.3.

slsnif is a serial line sniffer. It listens to the specified serial port and logs all data coming through it. slsnif works transparently for both the device connected to the serial port and the controlling software for this device. It operates by opening a pseudo tty (pty) and linking it to the actual serial port.
slsnif operates by opening a pty and linking it to the serial port. These are following parameters / options:
1. Serial port to open (required).
2. Name of the file to direct output to (optional, defaults to stdout).
3. Desired baudrate (optional, defaults to 9600 baud).
4. Timestamp On/Off (optional, defaults to Off).
5. Print ascii values in hex On/Off (optional, defaults to Off)
6. Print number of bytes transmitted On/Off (optional, defaults to Off).
7. Optional colors for timestamp, number of bytes transmitted and normal output.
8. Lock port On/Off (optional, defaults to On).
9. Use Unix98 ptys instead of BSD ptys (optional, defaults to BSD style).
10. Second serial port to open. If specified, this port will be used instead of a pty, thus providing an ability to log data between two serial ports.
Enhancements:
- Added ability to resynchronize ports at any time by sending a SIGUSR1 signal to slsnif. Useful for debugging applications that change port parameters mid-way, after starting the transmission. One example is pppd daemon, which sets initial parameters in the chat script, and changes them later, after chat script terminates.
- Added ability to use SYSV (Unix98) ptys instead of BSD ones (see -u and --unix98 parameters). This option can also be turned on/off from rc-file.

Serbert is a command line utility which performs a Bit Error Rate Test (BERT) on serial lines for Unix and its variants. It does this by transmitting bytes, and waiting for their uncorrupted return.

Serbert, however, does not provide a true Bit Error Rate Test (BERT), as it does not check the individual bits returned. It uses the operating systems standard serial interface, which provides the status of each returned byte.

THC-Shagg is a modular application to bruteforce check digit algorithms. THC-Shagg project can be used to gain information about serial numbers that use check digit algorithms.

Once THC-Shagg has analysed a set of serial numbers and found matching check digit algorithms, it is able to generate complete new serial numbers using a saved file containg the matched states.

This page demonstrates the use of THC-Shagg in "daily" life and lists some serial numbers, that have been successfully analysed using Shagg.

Development & Contributions

Youve found some serial numbers and were able to analyse the check digit algorithms using Shagg. Youve some new ideas, you know something about fresh or still un-implemented check digit algorithms. Contribute! And help us making THC Shagg more powerful. Feel free to drop an email to Plasmoid, plasmoid@thc.org.

If you are interested in joining THC, why not write some new classes for THC-Shagg or extend the current version to analyse Web session IDs or other serial numbers? The documented programming API to all classes and interfaces is available online. The source code for THC-Shagg is bundled with the current release, so that you can compile it yourself, if you want to.

How it works:

A check digit algorithm uses the digits of a serial number to construct a check digit, it is not necessary that the digits are numeric values, they can be extended to alpha-numeric values. THC-Shagg currently implements the following algorithms:

Full name Internal name
-------------------------------- ----------------
binary Modulus 7 DR Modulus 7
binary Modulus 9 DR Modulus 9
weighted Modulus 10 DR Modulus 10 Basic
weighted Modulus 10 Luhn Modulus 10 Luhn
weighted Modulus 10 IBM Modulus 10 CC
weighted Modulus 11 DSR Modulus 11

Future releases will implement more algorithms. To get a list of all available algorithms use the -A. For simplicity this version mixes binary and weighted algorithms, DR and DSR algorithms, future version of THC-Shagg may include separate options for binary, weighted, DR and DSR algorithms. As this is the first release, only the most common algorithms have been implemented.

For details on the concept of each algorithms consult the source code of THC-Shagg or browse the web, there are some good information covering these algorithms.

Most of the algorithms above operate using so called weights. Weights are just a sequence of numbers that are multiplied with the individual digits of the serial number to be checked. THC-Shagg generates all weights up to a specified length and checks the serial numbers against all of these weight using all algorithms.

Example: All weights up to length 3

1,2,3,4,5,6,7,8,9,
01,02,03,04,05,06,07,08,09,10,...99
001,002,003,004,005,006,007,...999

THC-Shagg ignores all weights that only consist of zeros because they result in fault-positives and are not used in check digit algorithms.

In order to find the position of a check digit, THC-Shagg splits the serial numbers into partitions. A partition has a head and a tail, these parts are ignored during analysis of the serial numbers. THC-Shagg generates all partitions up to a specified minimum length where length is the length of the part to be analyzed. The programs checks the serial number against these partitions using weights and algorithms.

Bio::SAGE::Comparison module compares data from serial analysis of gene expression (SAGE) libraries.

SYNOPSIS

use Bio::SAGE::Comparison;
$sage = Bio::SAGE::Comparison->new();

This module provides several tools for comparing data generated from serial analysis of gene expression (SAGE) libraries.

BACKGROUND

Serial analysis of gene expression (SAGE) is a molecular technique for generating a near-global snapshot of a cell population’s transcriptome. Briefly, the technique extracts short sequences at defined positions of transcribed mRNA. These short sequences are then paired to form ditags. The ditags are concatamerized to form long sequences that are then cloned. The cloned DNA is then sequenced. Bioinformatic techniques are then employed to determine the original short tag sequences, and to derive their progenitor mRNA. The number of times a particular tag is observed can be used to quantitate the amount of a particular transcript. The original technique was described by Velculescu et al. (1995) and utilized an ~14bp sequence tag. A modified protocol was introduced by Saha et al. (2002) that produced ~21bp tags.

PURPOSE

This module facilitates the comparison of SAGE libraries. Specifically:

1. Calculations for determining the statistical
significance of expression differences.
2. Dynamically convert longer-tag libraries to
a shorter type for comparison (e.g. comparing
a LongSAGE vs. a regular SAGE library).

Both regular SAGE (14mer tag) and LongSAGE (21mer tag) are supported by this module.

Statistical significance in library comparisons is calculated using the method described by Audic and Claverie (1997). Code was generated by directly porting the authors original C source.
